magnification is detected. Bitmap can be scaled up and translated on a View based on a Matrix object. A Matrix object is a Matrix used in android to implement geometric transformation of images. It supports common operations such as translation, amplification, reduction, miscutting, and rotation. Update and display of Bitmap objects in View By reloading the onDraw method, you can use canvas to draw Bitmap objects and use the view. invalidate () method to refresh views. Description of import
